 This very interesting plant, by far the most important 

 addition lately made to the British Marine Flora, was 

 covered on the 21si October, 1846, by Dr. John Cocke oi 

 Plymouth, among rejectamenta on the shore at Bovisand, 

 near Plymouth. A few days subsequently it was met with 

 in a neighbouring station by the Rev. W. 8. Hore, who at 

 the same time gathered the equally rare and curious I 

 pomitra Cabrera; and to the untiring perseverance of 

 these gentlemen, who, day by day. during the incl 

 month of November — in all weathers — visited the shore,
